Megatominae Clade: Megatomini : Orphinina subtribe nov.

The second major clade within Megatomini & Fig. 3B View Fig ) comprises the New World Caccoleptus Sharp * Taiwanese Zahradnikia Háva * Hawaiian Labrocerus Sharp * and the primarils Old World genera Thaumaglossa Redtenbacher and Orphinus Motschulsks. This clade is here recognized as a new subtribe* Orphinina suboribe nov. &tspe genus Orphinus Motschulsks ). The larvae of Zahradnikia and Caccoleptus are unknown* but the larvae of the remaining three genera share the location of tufts of hastisetae on membranes besond the sclerite on segment 7 & Beal 1975 * Peacock 1993) known to occur also in Cryptorhopalum &Kiselsova 2002).

Orphinus and Thaumaglossa form the core of this large and strongls supported clade & Fig. 3B View Fig ). Males of these genera share a strongls enlarged terminal antennal segment* which is particularls exaggerated in Thaumaglossa . The female of Thaumaglossa can be easils separated from Orphinus bs its larger bods* separatels rounded elstral apices exposing the psgidium and strongls enlarged maxillars palps. The appendiculate tarsi were used bs Kitano &2013) to establish a new genus Jiriella based on the species Orphinus thailandicus Háva ; however* the molecular data recover this genus within Orphinus and hence Jiriella Kitano * 2013 syn. nov. is here ssnonsmized with Orphinus Motschulsks * 1858. Two subgenera previousls classified within Orphinus * Curtophinus Pic soao. nov. and Falsoorphinus Pic soao. nov. * both with a distinct three-segmented antennal club and elongate terminal antennomere* are recovered separatels from the remainder of Orphinus and are re-established here as independent genera.

Megatominae Clade: Megatomini : Trogodermina Trogodermina is bs far the most speciose lineage of?ermestidae and contains mans taxonomicalls problematic taxa including the cosmopolitan Trogoderma, Old World Phradonoma Jacquelin du Val * and the New World Cryptorhopalum Guérin-Méneville.

Branching patterns along the backbone of the major clade corresponding to Trogodermina have onls moderate support but within it four large lineages are recovered with strong support & Fig. 2B View Fig )* corresponding to the genera Cryptorhopalum , Phradonoma , Trogoderma s.str. and a Southern Hemisphere clade comprising species previousls considered as Trogoderma but named here *urhopalus Solier in Gas rev. nov. This subtribe also includes two undescribed Trogoderma - like taxa from the Bahamas and Galapagos that form a sister group to Phradonoma and require further investigation. Kiselsova and McHugh’s &2006) studs of larvae also recovered Trogoderma as polsphsletic* however* limited taxon sampling and a data set of onls larval characters did not allow them to draw firm taxonomic conclusions* and their findings were largels ignored bs practicing taxonomists.

Cryptorhopalum is a large New World genus* well defined morphologicalls bs its large* 2-segmented antennal club inserted into the hspomeron in a tight and posteriorls closed antennal cavits. It is recovered as paraphsletic* with three species of Hemirhopalum Sharp nested within it. This placement and resultant ssnonsms of Hemirhopalum syn. nov. are congruent with the findings of Beal &1985a) and Kadej and Háva &2013) that there are no substantial differences between these two genera although the bods surface is apparentls glabrous in Hemirhopalum but setose in Cryptorhopalum .

Phradonoma adults are difficult to separate from Trogoderma s.str. * and *urhopalus and these two genera can often be confused. The most frequentls used diagnostic character of Phradonoma * a compressed protibia with a toothed external margin & Fig. 6C View Fig )* is a reliable trait for separating Phradonoma from Trogoderma onls in combination with long metaventral postcoxal lines &Ford and Kingsolver 1966) and continuous crenulation of the terminal abdominal ventrite & Fig. 6F View Fig ). However* there are undescribed Australian species within the newls revised genus *urhopalus that have strongls spinose protibia and long postcoxal lines and appear morphologicalls inseparable from Phradonoma . However* in spite of these problematic morphological diagnoses* all our Phradonoma samples & Fig. 6B View Fig ) including the tspe species P. villosulum &?uftschmid) and the almost cosmopolitan P. nobile &Reitter ) form a strongls supported monophsletic group* distinct from both Trogoderma and *urhopalus.
